Since an octopus's optic nerve passes behind the retina, its eyes have no such blind spot. The skin surrounding the wound tightens to close the area for the regeneration to begin. The octopus arm regeneration process starts as soon as the arm is lost or damaged. Even the physical structure of our eyes is nearly identical to that of an octopus, except for our "blind spot" where the optic nerve passes through the retina. Yes, an octopus can survive losing an arm, and as we’ve already discovered, whatever the cause was, the octopus can grow its arm back reasonably quickly. The parallels between humans and octopuses don't end there-our brains produce similar electrical patterns, feature complex folded lobes and are capable of short- and long-term memory.

Both humans and octopuses have a protein in their blood that carries oxygen hemoglobin for humans, and a copper-rich protein called hemocyanin in octopus blood, which gives it a distinctive blue color.

The blood then enters the main, or systemic, heart, which circulates the newly oxygenated blood throughout the body, like the left side of human hearts. Two of their three hearts, the branchial hearts, pump blood through the octopus's gills, where it releases carbon dioxide and absorbs vital oxygen-much like the right side of our heart passes blood through our lungs. Thus if it is missing the Health Check will result in a warning. The tentacles, or arms as theyve been more commonly called, are controlled via a neural transmitter chip which has been fused into his spinal cord.

Like humans, octopuses have closed circulatory systems, meaning that closed vessels or tubes transport blood throughout their body.
